Quantification of the final concentration of YRGDS in swollen PEGDA 3400 hydrogels as a function of precursor YRGDS concentration for various NVP concentrations. Hydrogels were formed using a 25% (w/v) PEGDA 3400 precursor solution and polymerized for one minute at 100 mW/cm2 (n = 3; * = p < 0.05 and # = p < 0.001).
